I've had original concepts I've tossed around for RP's that I've seen become comics sooner than later just because I only assume great minds think alike. Or somebody at the offices of DC is stalking me online. 

Case in point. Before Guildfall I tossed the idea around to Aro for a Justice League 3000 after our most recent Legion of Superheroes game [also set around the year 3000] was dying out. The idea was to take remaining members of Legion and make a new Justice League for the year 3000 with a few reimagined classics like the Flash and Superman. Literally months later DC announces a similar book, no Legion connection, but reimagined classics in a title called... Justice League 3000.

Another example, we spun a more modern Legion game in our 2020 universe [that was 2022 at this point] and it was to be our version of the Guardians of the Galaxy in the DC universe. I made a Green Lantern analog after writing out the Lanterns as not being recognized as an authority in several space sectors, he wore a cool jacket, no mask or GL badge, no ring but still had limited powers. Very Starlord like. What's DC doing in the comics now to Hal Jordan? Oh you know, just making him more like Starlord... hanging around in a cool coat with limited powers, no badge,  and no ring. 

It's not that nobody can have an original idea or a fresh take on an existing concept, it's just that there are as many others out there with the same influences coming up with the same types of characters and stories.
